Boxers who adapted to a more aggressive style?

We always see boxers throughout their career adapt and take one a more conservative and less offensive style in the ring. But who are some fighters that went from an outside fighter to an agressive power puncher?

Robert Gurerrero was a decent boxer who jumped 2 weight classes to go after a Mayweather fight. He mostly started brawling after the weight jump.

Not so much power punchers but guys who changed styles Marquez comes to mind.
Morales was a good boxer who had real skill but when the lights were on he loved to brawl and put on a show.
I always felt Cotto was another. Real boxing skills could have probably easily out boxed many opponents bit chose to be agressive especially early in his career.

Chris Algieri, however I didn't like his last performance.
